Model 42i (NO-NO2-NOx) Analyzer Thermo Scientific™

Measure levels of nitrogen oxide (NO-NO2-NOx) in the emissions from a source using chemiluminescent technology with the Thermo Scientific™ Model 42i NO-NO2-NOx Analyzer.

Discover the iQ to work smarter with our next generation 42iQ NO-NO2-NOx Analyzer.

Model 42i-TL TRACE Level NOx Analyzer Thermo Scientific™

Measure the amount of nitrogen oxides in the air from sub-ppb levels up to 1000 ppb using chemiluminescence with the Thermo Scientific™ Model 42i-TL TRACE Level NOx Analyzer. The Model 42i-TL is a single chamber, single photomultiplier tube design that cycles between the NO, NOx, and Zero modes. The addition of the Zero mode provides for excellent long term stability and extremely low minimum detectable limits. The 42i-TL has independent outputs for NO, NO2, and NOx and each can be calibrated independently.
